BEAM-COUPLING FOR CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 357,727, dated February 15,1887.

Application filed August 16, 1886. Serial No. 211,063. (No model.)

To aZZ whom it may concern: E represents the sections or halves forming Be it known that I, GILPIN MOORE, residing the vertical sleeve, each section or half having at Moline, in the county of Rock Island and at the end a lip, e, and one section having on State of Illinois, and a citizen of the United its exterior face a spline or rib, e.

fits the square portion of the hole in the yoke G, and the stem of which is screw-threaded and passes through the hole therefor in the yoke G and head or block I.

K is a nut for the bolt J, and having connected therewith by radiating arms the rim K, formed of balls and connectingbars to furnish ahold for the handin turning on or oft the nut.

L is the pipe-box, having a circular longitudinal hole for the passage of the spindle.

The parts are brought together by passing the sleeveE through the opening or hole thereforin the open endg of the yoke, the spline e entering the opening therefor in the ends 9, so as to lock the sleeve to the yoke against lateral turning, except when the two turn together, and at thesame time leaving the yoke free to be The bolt J is passed through the opening therefor in the yoke G, to have its stem receive the head or block I, which is slipped thereover for the yoke G to enter the opening or slot 2" between the wings i. The nut K is screwed onto the stem J back of the head I, and the head His slipped into place between the arms of the yoke G in contact with the sleeve E, which forms an opening between the blocks H I for the pipebox, which is slipped into such opening and locked by forcing the block I forward by the handnut K K, which firmly clamps the coupling onto the pipe-boX.

- In use the coupling is adjusted on the sleeve E to raise and lower the forward end of the plow-beam by loosening the hand-nut K Ksufficiently to release the bite of the block H on the sleeve E and allow the sleeve to be raised or lowered in the yoke G to the extent requi red for the adjustment of the running depth, and when properly adjusted the parts are locked by forcing the block H into biting contact with the sleeve E. The coupling is adjusted laterally on the pipe-box L to widen or narrow the distance between the gangs by loosening the handnut K K sufficiently to release the clasp of the blocks H I on the pipe-box and allow the lateral movement of the coupling on the pipebox L, and when the adjustment desired is attained the blocks H Iare tightened on the pipebox L by turning down the hand-nut K K. The lateral swing of the beam produces more or less wear of the sleeve-heads D in the bearings G, and the conical shape of the contactfaces of the heads and bearings through the draw of the rod F takes up the wear between the heads and the bearings by simply turning the nut f to draw the taper d of the heads D into contact with the taper c of the bearings 0, thus enabling the sleeve to be used until worn out without becoming loose and impaired in its workings by reason of looseness.

What I claim as new, and desire to secure by Letters Patent, is

1. The plate A B, provided with bearings O,

each with a taper, c, in combination with the sleeve E, formed of two halves or sections,each having a head, D, with a taper, d, and drawbolt F, for taking up the wear, substantially as specified.

2. The sleeve E, formed of two halves or sections, each having a head, D, with a taper, d, and the bearings (J, in combiuationwith the yoke G, and the clamping-block H, for adjusting and locking the yoke on the sleeve, substantially as specified.

GILPIN MOORE.
